I was 32 single, my sister was 34 and separated. We lived close to each other and both worked nights. After her separation she started dropping by my house. We started to open up sharing some of our deepest secrets, she told me she knew about me and our cousin having s**. I lost my virginity to our first cousin but I never knew she told anyone, especially my sister.
One day we were talking and she asked me if I had a fwb? I had somebody but I knew she wanted more so I was reluctant to get with her.
We got off the subject and was talking about something else when she said, you wanna do it with me? I said do what? She said f***, fwb. I was stunned waiting to see if she was joking but she just looked at me waiting for an answer. I said are you serious? She said yeah why not neither of us has anybody we’re not cheating. She never mentioned the i***** thing and neither did I we both approached it like we were friends. It was a little awkward that first time not knowing what you should or shouldn’t do. We did it for close to 2 years until she had met someone. I was a little jealous but kind of relieved because we had a couple of close calls and I felt like it was just a matter of time before someone found us out. We are in our 50s now, and we have stayed close, we never talk about what we did we don’t have to.
